The Casio MRW-230H is a contemporary dive-inspired timepiece that merges functional design with bold aesthetic appeal. Housed in a round 44mm black resin case, this quartz watch features a striking black dial accented by a distinctive orange and black unidirectional rotating bezel topped with an aluminium ring. Luminous hands and markers ensure readability in low-light conditions, while the integrated day-date display at 3 o'clock adds practical functionality for everyday wear.

FAQ

Q: Is this watch suitable for scuba diving?

A: With 100-metre water resistance, the MRW-230H is suitable for recreational diving, snorkelling, and swimming. It features a unidirectional rotating bezel for tracking dive time, though professional divers may prefer ISO-certified dive watches with higher depth ratings.


Q: How does the day-date display work?

A: The day-date window at 3 o'clock shows both the day of the week (abbreviated) and the numerical date. This is a mechanical calendar that advances automatically and can be adjusted via the crown.


Q: What type of battery does this watch use and how long will it last?

A: The MRW-230H uses a standard quartz watch battery. Typical battery life is approximately 3 years under normal use. Our team at Cassims & Co. can replace the battery when needed to maintain water resistance integrity.


Q: Is the bezel bidirectional or unidirectional?

A: The bezel is unidirectional, rotating only counter-clockwise. This is a safety feature standard on dive watches, preventing accidental adjustment that could overestimate remaining air supply during a dive.


Q: How do I activate the luminous feature?

A: The hands and hour markers are coated with luminous material that charges when exposed to light. Simply wear the watch in normal lighting conditions, and the lume will glow in darkness for enhanced visibility.


Q: Can I wear this watch while showering or in the pool?

A: Yes, 100-metre water resistance means the watch is perfectly safe for showering, swimming, and water sports. Avoid operating the crown or buttons while the watch is wet or submerged.


Q: What wrist size does this watch fit?

A: The resin strap is designed to accommodate a wide range of wrist sizes comfortably. For specific sizing or strap adjustments, please contact our team or visit us in store for personalised fitting assistance.
